Abstract: 1308344 Producing sintered dies or moulds TOYATO CHUO KENKYUSHO KK 30 Oct 1970 [8 Nov 1969] 51677/70 Heading C7D [Also in Division B3] A sintered mould or die with an internal cooling channel is made by packing a metal powder around a former and a metal pattern which correspond to the required die shape and channel respectively and then heating the assembly to sinter the powder and infiltrate the metal pattern into the powder. The powder may be Fe-C, Fe, Cu, Cu alloy, WC or TiC and the metal pattern may be Cu, Cu-Mn, Cu-Co, Pb, Pb-Sn, Pb-Cd, Co, Ni, Fe alloy, Ni-Mo or Co alloy, the metal of the pattern fusing below the sintering temperature of the powder. The former may be a ceramic or a metal e.g. Cu which also infiltrates the powder during sintering. As shown in Figs. 1 and 4-7, a split mould with a lower mould 721, an upper mould 722 and a cooling channel 111 is formed by placing a Cu pattern 11 on a layer of Fe powder in a ceramic frame 31 which has been coated with Al 2 O 3 . After covering the pattern with Fe powder, the Al 2 O 3  coated former 6 is placed in the powder and further Fe powder is added to form the layer 71. Formers 65 coated with Al 2 O 3  are inserted into the powder for forming guides 765, 766 and the surface of layer 71 is coated with Al 2 O powder 8 before covering with Fe powder 72. Cu pattern 21 is then placed inside the former 6 and covered with Fe powder. The assembly is compacted at 0À8t. sq.cm and sintered at 1120 C. in N 2  with or without frame 31. After sintering, upper layer 72 is easily removed from lower layer 71 and formers 6 and 65 are also removed to leave the sintered two piece mould.

Filed: 1974-11-29
Abstract: 1484619 Ultrasonic inspection devices KRAUTKRAMER-BRANSON Inc 29 Nov 1974 [13 Feb 1974] 51768/74 Heading G1G In the ultrasonic pulse-echo inspection of a workpiece, defect echo signals are fed to gate circuits controlled such that, at any time, one is open and the rest are closed. The trailing edge of each echo signal controls the closure of the open gate and the simultaneous opening of a formerly-closed gate, whereby the gates are opened in turn in a given sequence. Following transmission of a pulse by transducer 14 in the Fig. 1 embodiment, ring counter 32 is enabled by a signal at 29 during the expected echo train reception period. The first echo passes through open gate 36 to sample and hold circuit 42 where its peak, or RMS, amplitude is stored. The trailing edge of the echo, sensed by threshold circuit 24 and SR flip-flop 48, clocks the ring counter, thereby closing gate 36 and opening gate 38 for passage of the second echo. Subsequent echoes pass respectively through gate 40 and further gates (not shown), their trailing edges clocking counter 32 in the same way as the first and second echoes. The resulting stored echo amplitude values from 42, 44, 46 &c. are then optionally converted to digital form by respective A/D converters or by multi-plexing them at 50 into a single A/D converter 58. The multi-plexing commences at the trailing edge of the enabling signal on line  29. The digitized values are stored in memory 54, together with values from counter/timer 66 indicative of the depths of the associated defects in the workpiece. The data stored in memory 54 can be read out for averaging to evaluate the porosity and strength of the workpiece. Counter 32 is reset to zero by the enabling signal trailing edge. A binary counter and de-coder can be used instead of counter 32.
